Method and system for classifying image elements

摘要

A method, system, and machine-readable medium for classifying an image element as one of a plurality of categories, including assigning the image element based on a ratio between an unoccluded perimeter of the image element and an occluded perimeter of the image element and coding the image element according to a coding scheme associated with the category to which the image element is classified. Exemplary applications include image compression, where categories include image foreground and background layers.

1. A method comprising:
identifying a first image element of an image as a background and a second image element of the image as a foreground; and encoding, via a processor, the first image element using a number of bits that is proportional to a length of un-occluded perimeter segments of the first image element relative to a length of occluded perimeter segments of the first image element that result from occlusions by foreground elements of the second image element.
